As a vehicle car wash device that can wash any of
One described in Japanese Utility Model Laid-Open No. 1-11062 is known.

(3) Problems to be Solved by the Invention By the way, the above-mentioned conventional vehicle cleaning device is used for a vehicle having a high vehicle height such as a sheep type vehicle or a wagon vehicle type vehicle and a passenger vehicle type vehicle by the vehicle height detecting means. A vehicle having a low vehicle height is identified, and when a vehicle having a high vehicle height is detected, cleaning is performed with the upper brush held at the upper limit position.

However, since the conventional vehicle cleaning device cannot distinguish between a jeep type vehicle and a wagon vehicle type vehicle, both of which have a high vehicle height, for example, the upper surface brush is adjusted to an optimal height according to the shape of the vehicle body. There is a disadvantage that cannot be controlled.

The present invention has been made in view of the above circumstances, and detects a front shape of a vehicle in a car washer capable of reliably distinguishing vehicles having different front shapes, such as a jeep type vehicle and a wagon type vehicle. It is intended to provide a device.

B. Configuration of the Invention (1) Means for Solving the Problems In order to achieve the above-described object, a front-surface shape detection device for a vehicle in a car washer according to the present invention cleans the vehicle while moving relative to the vehicle. A car washer disposed at a position higher than a hood surface of a jeep type vehicle, and an upper body detecting means for detecting a portion higher than the hood surface of a jeep type vehicle and a wagon type vehicle; A front shape determining means for determining a front shape of the vehicle based on a relative momentum from a state in which the vehicle body upper portion detecting means detects the vehicle to a state in which the vehicle has a predetermined positional relationship. .

In addition, the vehicle front shape detection device in the car washer according to the present invention is a vehicle washer for washing the vehicle while relatively moving with respect to the vehicle, wherein a car body end detection unit that detects a front end of the vehicle, a jeep type vehicle The vehicle body upper detecting means is disposed at a position higher than the hood surface of the jeep type vehicle and the wagon vehicle type vehicle and detects a portion higher than the hood surface of the jeep type vehicle and the wagon type vehicle. A second feature is that it comprises a front shape determining means for determining the front shape of the vehicle based on the signal.

(2) Operation According to the first feature of the present invention having the above-described configuration, when the upper body detecting means detects a portion higher than the hood surface of the vehicle by the relative movement between the car washer and the vehicle, the jeep having the hood is provided. The timing at which the detection unit outputs the detection signal differs between the vehicle of the type and the vehicle of the wagon type without the hood. Therefore, the relative movement amount from the state where the car washer and the vehicle are in a predetermined positional relationship to the position where the upper body detecting means outputs a detection signal occurs depending on the front shape of the vehicle, and the front shape is determined based on the difference. The determining means distinguishes between a jeep type vehicle and a wagon type vehicle.

Further, according to the second aspect of the present invention, when the upper body detecting means detects a portion higher than the hood surface of the vehicle by the relative movement between the car washer and the vehicle, the vehicle does not have the jeep type vehicle having the hood and the hood. The timing at which the detection unit outputs the detection signal differs from the wagon type vehicle. Therefore, depending on the front shape of the vehicle, there is a difference between the timing at which the body end detecting means detects the front end of the vehicle and the timing at which the upper body detecting means detects the upper part of the vehicle. Distinguishes between jeep type vehicles and wagon type vehicles.

It may be one that detects the power and rotation speed of ten.

Next, the first cleaning step of cleaning Jeep type vehicle V _2, will be described with reference to FIG. 5 and FIG. 9.

The cylinder 19 is deactivated and the swing shaft 6 is moved 6a from the position 6c.
The upper surface brush 7 that has been rotating at the upper limit position of (L) is lowered to the lower limit position of (E) by lowering to
The gate-shaped traveling frame 1 starts going forward (step S1).
Four). Top brush 7 abuts against the front of the vehicle V ₂ reaches the position of (Wa), that the swing arm 5 exceeds a third deflection angle (about 30 degree angle from the vertical line through the pivot shaft 6) When the swing angle is detected by the swing angle detecting device H (step S15), the swing shaft 6 is rotated counterclockwise (step S16). When the swing shaft 6 moves up to the intermediate position 6b and the upper brush 7 reaches the position (f) (step S17), if it has not exceeded the third swing angle (step S18), the swing shaft 6 is stopped at that position (step S19). On the other hand, when the swing angle exceeds the third swing angle in step S18, the swing shaft 6 further rotates (step S20), and when the swing shaft 6 reaches the upper limit position 6c (step S21), the swing increases. Stopped (Step S2
2). Top brush 7 in this way to wash a bonnet surface of the vehicle V _2. When the upper brush 7 reaches the position (ta) where it contacts the windshield surface and exceeds the second deflection angle (step S23), the above-mentioned wagon vehicle type vehicle V ₃
In the same manner as in the case of cleaning, the same operations as those in steps S7 to S11 in FIG. 6 are performed (steps S24 to S2)
8). As a result, the upper brush 7 moves from the position (T) to the position (V) to clean the windshield surface, and after reaching the ceiling surface at the position (G), following the ceiling surface ( (2), (4) and (4) are moved.

Figure 10 is a flowchart of a second cleaning step of cleaning Jeep type vehicle V _2, the cleaning step is the second cleaning step wagon type vehicle described above (see FIG. 7)
Similarly to step S2 in the flowchart of FIG.
The "2nd run detection?" Of 3 has been changed to "load detection" in step S23-A, and is different only in that in the case of NO, the process proceeds to "end of travel" in step S29. . Therefore, the operation after step S23-A is the same as the operation after step S6-A in the flowchart of FIG.
